Yes and No!

After applied the patch and changed settings it started to work.
But there seems to be things that is not right.
Evolution makes sever attempts to login -> all with socket closed
If I remove the script (see below) THEN IT'S OKAY.

dovecot is executed as root.

dovecot.conf

protocols = imap pop3 
base_dir = /var/run/dovecot/
#base_dir = /home/fetchmail/

log_path = /var/log/dovecot.log
info_log_path = /var/log/dovecot-info.log

ssl = no # v1.2+, for older versions use: ssl_disable = yes
disable_plaintext_auth = no

mail_location = maildir:/home/fetchmail/mailroot/dummy

pop3_uidl_format = %08Xu%08Xv


!include conf.d/*.conf

service imap {
  executable = imap imap-postlogin
}

service imap-postlogin {
  executable = script-login /home/fetchmail/dovecot-postlogin.sh
  unix_listener imap-postlogin {
  }
}

dovecot-postlogin.sh    (executed as root)
=============
#!/bin/sh

kill -s 10 `cat /home/fetchmail/.fetchmail.pid | head -n 1` >>/home/fetchmail/script.log

exit 0
